1841 (Sept 3) Registered cover sent to Vallenar from Copiapó, addressed to the Judge of Justice Santiago Zavala of the Vallenar courts, from the Copiapó Court, with rare “Certificasion” straight line mark in red, “Franco” hs in red, and the “Copiapó” straight line hs also in red (S.F.C. MPF9), with manuscript crossed triangles to the four corners denoting registration, contains interesting letter, tear top and piece missing centrally at the base, but these do not detract from this attractive, rare and important cover; only six or seven registered covers recorded from the pre-philatelic period.
